[1238] AVPro Video Player has a recursion bug when changing URL's in beta build.

There's an infinite loop bug in the AVPro video player that will crash out the Udon script controlling it.
I've tested against the Live version and confirmed it works without issue, and tested on the current open beta with a stock AVPro video player prefab from the VRChat SDK to confirm the fault is in the AVPro video player and not something I've done in Udon myself.
To reproduce; Play a youtube video. Now play another one, or a twitch stream. It will get very angry and crash out immediately. Looking in the log, it seems like something is broken inside yt-dlp.exe?

You posted this to the wrong board. I moved it to the Open Beta board.

Tupper - VRChat Head of Community: My bad, and thanks.

Can you provide a world ID?
Whaddageek
Tupper - VRChat Head of Community: Sure, but it's been world-agnostic. - I've tested in several of my worlds using a stock AVPro player to make sure it wasn't something I did.
You're welcome to try in my world though. The Videoplayer uses a slight tweak of the stock AVPro player provided in the SDK, but all it does is add play/pause/stop options, actual video-management code is untouched (I've reasonably excluded it being my fault as it was working fine pre-patch and replicated the results exactly with a stock AVPro player).
Video player is up the stairs, through door on the right to the Lounge Room, and it's in the big mirror on the wall (panel on the left-hand side, third button down)

Tupper - VRChat Head of Community: Tried again on the new build (1240), and AVPro player is now working correctly!
